Mercer Rubber Company, established in 1866, is the oldest U.S. manufacturer of rubber expansion joints, flexible duct connectors and industrial hose. All connectors are hand built to the highest standards.
Mercer has successfully analysed and designed a wide range of products for demanding applications. Our specialty is developing custom products for a specific job, from a single small joint to hundreds of large diameter joints needed for power generating projects.
Hand built flexible connectors for piping and duct work solve problems that cannot be handled by other materials. Rubber is more compliant and resilient than metal, fiberglass or plastic. The technology behind building shapes for industrial applications has grown as well. Modern reinforcement fabrics and tire cord have completely replaced early designs using cotton and rayon. The end result has been a lighter, more flexible, higher pressure and temperature resistant product.
Rubber expansion joints are capable of axial compression, axial expansion, transverse and angular movements. In many cases, three movements are all taking place at one time. Standard expansion joints have movement limits, but they can be increased by changing to multiple arches or single piece construction with an arch at each end and a long intermediate hose body.
Mercer Connectors have great flexibility and have higher limits the other products.
Mercer has extensive experience in the Power, Wastewater treatment, Industrial and Chemical Industries, as well as HVAC Commercial and Marine work. These customers rely on Mercer products for high reliability and a long, virtually maintenance free life. Have a large project?
